Size

The size (diameter) of the main subwoofer speaker. In all types of subwoofers, this parameter primarily affects the power and depth of sound: the larger the speaker, the louder it is and the deeper the bass it can provide (ceteris paribus). However with an increase in the size and dimensions, they increase accordingly, which determines the installation possibilities. The latter is especially true in Free Air subwoofers (see "Execution"): some cars are initially equipped with "seats" for a certain size, and it is difficult to install models with other dimensions there.

Now on the market there are subwoofers with such popular sizes: 5" (13 cm), 6" (15.25 cm), 6.3" (16 cm), 6.5" (16.5 cm), 6.75" (17 cm), 8" (20 cm ), 8.25"(21cm) , 9" (23cm ), 10" (25cm ), 11" (27cm), 12"(30cm) , 13" (33cm), 15"(38cm) , 16 " (40 cm), 18" (46 cm).

Rated power

The average (root mean square — RMS) power of the input signal, at which the subwoofer is able to work continuously without negative consequences (damage, failure) for at least an hour. The rated power of the subwoofer must be greater than the power of the amplifier connected to it — in order to avoid overloads.

Max. power

The maximum signal power that the subwoofer is able to withstand for a short time (up to several seconds) without any negative consequences. When selecting an amplifier-subwoofer pair, it is recommended to take a subwoofer with a maximum power of at least twice the maximum power of the amplifier. In general, the higher the maximum power, the more resistant the subwoofer is to overloads.
